Specification of Letters Patent.

Patented Oct. 17, 1905.

Application filed July 21, 1905. Serial No. 270,646.

, The invention resides in novel mechanism whereby a body of liquid may be cooled very quickly, such mechanism being adapted to be power-driven or for automatic operation, as

will be pointed out more clearly hereinafter.

For a full description of the invention and the merits thereof and also to acquire a knowledge of the details of construction of the means for effecting the result reference is to be had to the following description and accompanying drawings, in which Figure 1 is a perspective view of anapparatus embodying the essential features of this invention. Fig. 2 is an end elevation of the invention, portions of the same being shown in section, bringing out clearly the arrangement of parts. Fig. 3 is an end elevation looking from the end opposite that shown in Fig. 2. Fig. i is a horizontal sectional view. Fig. 5 is a broken view in elevation of the clutch mechanism whereby the apparatus may be thrown into and out of automatic operation. Fig. 6 is a view similar to Fig. 5, showing the means whereby the apparatus may be operably connected with power-driven mechanism. Fig. 7 is a perspective view of the cooling-coil.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

Referring to the drawings, the numeral 1 designates a cooling-tank, which may be supported in any substantial way as, for instance, upon the legs 2 illustrated. The cooling-tank 1 surrounds the cream-vat 3, which is spaced fromthe tank 1, forming a liquidchamber 4 between said parts 1 and 3. A

small trough 5 at the upper portion of the cooling-tank 1 and at an end thereof is open, so as to admit of supplying a liquid, such as a cooling medium, to the chamber 4: aforesaid. Arranged for movement in the vat 3 is a cooling-coil 6, which may be of any conventional type and preferably receives the cooling medium, such as water, at one end, the water circulating through the various coiled portions of the coil and passing out of the other end.

For the above purpose an inlet-pipe 7 communicates with a header 8 at one end of the coil 6, and said pipe 7 may be connected with a hose or flexible tubing 9, connected to the liquid-supply, said flexible tubing 9 permitting of free up-and-down movement of the 00116. An outlet-pipe 10 extends from the header 8 at the end of the coil 6 opposite that having the inlet-pipe-7 adjacent thereto, the upper extremity of the pipe 10 being curved to form a spout 11, which is arranged above the trough 5, so as to supply liquid to the trough, from which it runs into chamber A rod 12 may connect the pipes 7 and 10 to brace the same.- Water or other cooling medium passing into the coil 6 at 7 passes from the coil at the spout l1 and into the coolingchamber 4 between the vat 3 and the cooling-tank 1. The liquid in the chamber 4 will be maintained at a depth corresponding with the depth of the cream or other liquid which is being cooled and aerated in the vat 3. The liquid after passing into the chamber i'passes from this chamber at the bottom thereof through an outlet-pipe 13, which extends longitudinally of the tank 1 beneath the same. The pipe 13 connects with a vertical pipe 14: at one end of the tank 1, said vertical pipe 14 having a stufiing-box 15 at its upper end portion, in which is telescopically mounted a short pipe 16. The pipe 16 leads into the bottom of a distributing-tank 17, which is adjustably supported at this end of the tank 1 by means of a vertically-slotted bracket 18. The bracket 18 is adjustably secured, by means of a nut 19, to a vertical standard 20, which is one of a pair of standards 20 and 21, located at one end of the tank 1 and supporting certain operating mechanism to be described. The distributing-tank 17 is provided with outlets 22 at opposite ends thereof, and these outlets are adapted to be closed and opened by means of valves 23, the stems 24 of which are connected at the upper end thereof with a tilting valve-lever 25. The-lever 25 is fulcrumed between its ends, as shown at 26, in bearing-lugs 27, projecting upwardly from the inner and outer sides of the tank 17. Offstanding integral journals 28 support the lever 25 in the bearings 27 and tilting movement of the lever 25 will simultaneously open and close the opposite valves 23 in a manner which will be clearly evident. The outlets 22 of the tank 17 are each arranged above vertically-movableliquid-receptacles29. The receptacles 29 are suspended by means of U- shaped vertical rods 30, the lower extremities of which are attached to the bottom of the receptacles and the upper extremites of which are connected with opposite ends of a sprocket-chain or similar flexible connection 31, which passes over sprocket-wheels 32 and 33 at the upper ends of the standards 20 and 21. The sprocket-wheel 33 is supported on a short shaft 34, mounted in a bracket 35, attached to the upper end of the standard 21. The outer end of the shaft 34 carries a toothed segment 36, in mesh with apinion 37, mounted just beneath the segment, said pinion having an ofl'standing boss 38, from which projects an arm 39, carrying a weight 40 upon its outer end. The sprocket-wheel 32, however, is carried by an end of ashaft 41, which is mounted in the upper ends of the standard 20,'and a similar standard 42, which projects upwardly from the tank 1 at the end opposite that at which the standard 20 is located. The shaft 41 is journaled in suitable bearings at the upper ends of the standards 20 and 42, and said shaft is provided with two sprocket-wheels 43 near opposite ends thereof, chains 44 passing over the sprocket-wheels 43, said chains being connected at one end with hooks 45, which are carried by the upper end portions of the pipes 7 and 10, the opposite ends of the chains 44 supporting counterbalanceweights 45. It will be noted that the chains 44 connect the cooling-coil 6 with the shaft 41, and said shaft is adapted to be automatically operated by the movable receptacles 29 in order to impart vertical movement to the coil 6, and thereby force the coil through the cream or liquid which is being cooled or ops erated upon in the vat 3.

Asthe water or cooling liquid passes through the coil 6, from thence into the chamber 4, it then passes to the distributing-tank 17. When one end of the valves 23 in the tank 17 is closed, the other is open so as to permit the liquid which passes to the tank 17 to pass through an outlet 22 into the receptacle 29 below said outlet. The water or liquid passing to one of the receptacles 29 by its weight will cause said receptacle to lower until it reaches a predetermined point in its lowering movement, when an actuating-rod 46, one of which is carried by each receptacle 29, comes into contact with an adjustable tripping-arm 47. Each of the actuating-rods 46 is secured at one end to a side of the. receptacle 29, the opposite end having connection with a valve-stem 48, carried by a valve 49, one of which is provided to close an outlet in the bottom of each of the receptacles 29. Suitable guides 50 coact with an end of each actuating-rod 46 to direct its vertical movement, and as soon as the rod 46 strikes the arm 47, adjacent the receptacle 29, which carries said rod 46, the valve 49 connected with this rod will be raised so as to open the outlet 51 of the receptacle 29 aforesaid, thereby permitting the liquid conveyed by the receptacle to pass therefrom. It will be noted that as the receptacles 29 are connected together when one receptacle lowers the other is being raised in emptied condition, having previously discharged its contents at the limit of its lowering movement, and thus the operation of the two receptacles 29 will cause the shaft 41 to rotate, raising and lowering the coil 6 in the body of the liquid which is being cooled or treated in the vat 3. The lever 25, however, is automatically operated in the movement of the receptacles 29, so that when one receptacle reaches the limit of its upward movement in empty condition said lever 25 will be actuated to open the valve 23 above the empty receptacle 29 and permit the liquid in the tank 17 to pass therefrom to said empty receptacle. Meanwhile as the valve 23 aforementioned is opened the other valve 23 above the receptacle 29, which is moving downwardly in filled condition, is closed, shutting off the supply of liquid thereto. To effect the automatic operation of the lever 25, one of the receptacles 29 is provided with an offstanding arm 52 and adapted to engage pins or stops 53, carried by a vertical rod 54, which is movable through a slot in the arm 52 and which is connected at its upper end with a lug 55, projecting laterally from an end portion of the lever 25. The stops 52 are pins which are adjustable in a plurality of vertical openings 56 in the rod 54, and the adjustment of these stops will permit the lever 25 to be tilted at different points in the movement of the receptacles 29 in the automatic operation of said lever, as above described. One of the journals 28 has a collar 57 aflixed to its outer end, from which projects an arm carrying a weight 58. Thus as the lever 25 is tilted the shifting of the weight 28, which is actuated in the movement of the lever from one side of the fulcrum of the lever to the other, causes a quick closing and opening of the valves 23 at the proper time. The tripping-arms 47 project laterally from vertically-slotted plates 58, which are vertically adjustable upon opposite sides of the tank 1. Laterally-projecting guide-brackets 59 extend from the end of the tank 1, adjacent which the receptacles 29 operate, and these brackets coact with the rods 30 to direct thelatter in their vertical movement. The weight 40, which is mounted upon the pinion 37, is designed to necessitate filling of the receptacles 29 with more liquid than is necessary to raise and lower the coil 6. The above will cause the coil 6 to move quickly when it is actuated be cause of the weight of the filled receptacle 29 and the above causes the cream or liquid in the vat 3 to be stirred more effectively. When IIO the automatic mechanism comprised in the receptacles 29 and parts connected and actuated therewith is operabl y connected with the shaft 41, a clutch-sleeve on the end of the shaft between the adjacent wheels 32 and 43 is in a position in which it is interlocked with a clutch member 61, projecting from the hub of the wheel 32. The sleeve 60 is normally rotatable with the shaft 41, pins 62 operably connecting with sleeve with said shaft. A lever 63, pivoted to the outside of the standard 20, connects with the clutch-sleeve 60 for operation of the same, and a pin 6 L on a bracket 65, attached to said standard 20, will hold the lever 63 in aposition with the clutchsleeve 60 in or out of connection with the wheel 32. When the coil 6 is being raised and lowered by power-driven mechanism, the shaft 41 is connected by a pinion 65 upon the end thereof opposite that carrying the wheel 32 with rack-teeth 66 at the upper portion of a pitman 67, which moves adjacent the outer side of the standard 42. The pinion 65, which is keyed to the shaft 41, is affixed in its relative position; but the pitman 67 is adapted for movement to throw the rackteeth 66 thereof into and out of mesh with said pinion 65. A lever 68, pivoted upon the upper portion of the standard 42, carries a yoke 69 at its upper end, said yoke having rollers 70 journaled at opposite ends thereof in the sides of the yoke. The rollers 7 0 receive the rack portion of the pitman 67 therebetween, yet permit of free movement of the pitman as it is actuated by the power mechanism. By movement of the lever 68 the rack-teeth 66 may be thrown into or out of engagement with the pinion 65 when the lever is positioned by means of a pin 71, adapted to engage the lower end thereof. The lower end of the pitman 67 is connected adjustably with a crank-wheel 72, supported by a short shaft at the adjacent end of the tank 1. The wrist-pin '73 of the wheel 72 is adjust able longitudinally in a slotted plate 74, affixed to the outer side of the wheel 72 by means of an adjusting-nut 75. The adjustment of the point of connection of the pitman 67 of the wheel 72 will vary the stroke of the pitman in an obvious manner, and as the pitman is connected with the shaft 4:1 for act ation thereof the adjustment of the pitman permits of varying the extent of raising and loweringmovement of the coil '6. A

r w-off cook 76 is located at the end of the k 1 adjacent the standard 12 and permits the drawing off of liquid from the chamber 4.

It will be understood that the power-driven mechanism may be connected with the wheel 72 in any suitable way, and such mechanism may be used independently of the automatically-operated mechanism according to the desire of the operator of the apparatus.

It is to be understood that though the invention is primarily designed as a cooler of liquids, yet if cream or similar liquid be too cool to be operated upon and secure the best results it is obvious that a heating liquid may pass through the coil 6, chamber 4, and tank 17 and operate the same in exactly the same way as would be accomplished by the use of a cooling fluid. The term cooling used in this specification is not to be construed as a limitation in view of the foregoing.

As shown most clearly in Fig. t of the drawings, the cooling-coil 6 is of peculiar formation, including a plurality of longitudinal cooling-pipes 6*, arranged in spaced parallel re lation and connected at opposite ends to the opposite headers 8. The headers 8 are of tubular form, and the various pipes 6 are connected at the ends by short curved return-pipes 6 arranged in the tubular headers 8. One of the pipes 6 communicates with the interior of the header 8, which is connected with the inlet-pipe7, this pipe 6 being one of the outermo st pipes of the coil. The header 8, which is connected with the outlet-pipe 10, is likewise in communication with the pipe 6 at the opposite outmost portion of the coil, so that the cooling medium passing into the header 8 from the pipe 7 will pass through all of the pipes 6, first entering the outermost of the said pipes, passing from the pipes 6 to the header 8, connecting with the pipe 10 through the opposite outermost of said pipes 61. The return-pipes 6 being in the headers 8 are kept cool by the flowing cooling medium to a maximum degree of cooling of the coil is se cured in a manner which will be evident.

The term cooling-coil as used herein is to be understood as a member having the general function of a cooling means and agitator for the liquid being operated upon.
